Abstract (en)
[origin: EP3450008A1] A polyolefin production system comprises a plurality of gas-phase polymerization tanks configured to polymerize an olefin gas to form a polyolefin; a compressor comprising an inlet and an outlet and being configured to compress a an olefin-containing gas; an individual gas feed line disposed at each of the gas-phase polymerization tanks, configured to guide the gas fed from the outlet of the compressor to each of the gas-phase polymerization tanks; an individual gas discharge line disposed at each of the gas-phase polymerization tanks, discharging the gas from each of the gas-phase polymerization tanks; and a first valve installed in each of the individual gas feed lines.
